Failure to estimate row count for table with delimited id

[Barry Fritchman]

When a fully qualified table name includes a delimited identifier, estimation of the row count fails and returns the default cardinality estimate.

    Make corrections to HFile path

    To estimate the row count for an HBase table, the HFiles are
    accessed directly from the HDFS file system. When the Trafodion
    name of the table includes a delimited id, the quotes must not
    be included in the node of the HDFS path representing the
    qualified table name. In addition, the hbase.rootdir property
    in hbase-site.xml may consist solely of a path rather than a
    full URL. It was previously assumed that a full URL would be
    present, and the value of the property was used to construct
    a java.net.URI object. When a string consisting of only a file
    path is passed to the URI constructor, a NullPointerException
    is thrown (instead of the expected URISyntaxException), causing
    the path we construct to the HFile to be incorrect. The code
    was changed to utilize either a file path or a valid URI as the
    value of the property.
